find more robust way to apply corrections (React)

[danielnaber]

Several sites stop working correctly when the correction gets applied, e.g. Wikipedia (Visual Editor), upwork chat, Facebook (#70). We need a better way to apply the suggestion, maybe by simulating user input. If this is too difficult, we should detect the situation and turn off the add-on or show an error message.

This problem also appears in the NEOS content management system. If I correct mistakes with the add-on, NEOS doesn't publish the changes, I have to correct the text manually. Simulating user input might really be the best way (if possible).
